Abstract: PROBLEM TO BE SOLVED: To provide a radio communication system (20) which includes using a plurality of antennas (30, 32) in order to perform simultaneous transmission to a plurality of mobile stations (24, 26). SOLUTION: A distributed multiple antenna scheduling (DMAS) technique includes selecting the plurality of mobile stations which receive at least simultaneous transmission on at least one selected subcarrier from the inside of a carrier bandwidth having orthogonal frequency division multiplexing (OFDM). In a disclosed embodiment, the plurality of mobile stations are selected for each subcarrier in the carrier bandwidth. The embodiment includes grouping the subcarriers into a subset together in order to reduce complicatedness of calculation for determining which mobile station should be selected for the simultaneous transmission.

Abstract: PROBLEM TO BE SOLVED: To provide a method by which a plurality of subscriber's apparatuses is scheduled based on channel conditions and calculated power allocations against the downlink channel of the air interface of a radio communication channel so as to meet a desired system requirement. SOLUTION: In this method, a subscriber requesting an access right to a communication system or having a given access right to the system is selected by means of a scheduler based on the state of a channel and power allocation calculation. The scheduler achieves the desired system requirement by scheduling a selected group of subscribers and, consequently, the subscribers can simultaneously receive information from a plurality of antennas at a bas station.

Abstract: PROBLEM TO BE SOLVED: To provide a method for scheduling subscriber equipment to increase the system capacity. SOLUTION: A method for scheduling a plurality of subscriber equipment is performed on the basis of channel conditions of uplink channels and downlink channels of an air interface of a wireless communications system. The scheduled subscriber equipment can transmit information simultaneously at the desired information rate via the air interface to the plurality of antennas. The base station is provided with a plurality of antennas, and the subscriber equipment is provided with one antenna.

Abstract: PROBLEM TO BE SOLVED: To provide a method for realizing scheduling of a plurality of subscribers independently and increasing a capacity and a throughput of a HDR wireless communication system. SOLUTION: Each scheduler is related with an antenna and base-station facility for receiving a channel state as a base for subscriber's scheduling. This method includes a step of preparing a plurality of schedulers for carrying out scheduling of a subscriber independently from another subscriber on the basis of the channel state transmitted from the subscriber. The channel condition is treated by the base-station facility and scheduled by the scheduler.

Abstract: A flexible communications systems provides users with additional communication channels without requiring additional transmitters or receivers by using variable rate Walsh coding. Additionally, the assignment of these additional communication channels is easily managed at the base station by monitoring data backlog and receiver error rates.

Abstract: The present invention provides a method for reducing transmitted energy based on early decoding. The method includes accessing a first portion of a block including a plurality of symbols indicative of an encoded message. The first portion has been transmitted at a first transmission power and having less than all of the plurality of symbols. The method also includes attempting to decode the encoded message using the first portion of the block, determining whether the encoded message was decoded, and providing an indication of a second transmission power in response to determining that the encoded message was decoded.
